Description
Technical field
The present invention relates to be used to provide MBMS mobile communication system, radio control unit, portable terminal and the message method of (multimedia broadcast multicast service).
Background technology
In recent years, be used for having dropped into actual use by the service that is called as MBMS that the broadcast or multicast transmission is distributed the multi-medium data (hereinafter referred to as the MBMS data) such as film and music data simultaneously to a plurality of portable terminals.
Fig. 1 shows the configuration of the mobile communication system that MBMS can be provided.Configuration shown in Figure 1 is by 3GPP (the 3rd generation partner program) regulation.
As shown in Figure 1, mobile communication system comprises the UTRAN (universal terrestrial radio access network) 10 that is connected to CN (core network) 40.CN 40 has SGSN (Serving GPRS Support Node) 50 at the tie point place of itself and UTRAN 10.
UTRAN 10 comprises RNC (radio network controller) 20 and Node B (base station apparatus) 30.Each Node B 30 is used to cover a sub-district or a plurality of sub-district, and is connected to UE (subscriber equipment) 60 by radio interface.
When the mobile communication system with above-mentioned structure began MBMS is provided, RNC 20 sent MBMS MODIFIED SERVICES INFORMATION message to the UE 60 that pays close attention to MBMS, so that notifying MBMS will be activated, and begins to distribute the MBMS data subsequently.In the time will making other changes to MBMS, for example in the time will finishing MBMS, RNC 20 also sends MBMS MODIFIED SERVICES INFORMATION message to UE 60.
According to a kind of method that sends MBMS MODIFIED SERVICES INFORMATION message, for example,, use MCCH (1 of MBMS arrives the multiple spot control channel) as disclosed in the patent documentation 1.Usually, when UE 60 set up individual channels (Cell_DCH), UE 60 can receive individual channels DPDCH, but can not receive common signal channel S-CCPCH.MCCH is mapped on the S-CCPCH.Therefore, when UE 60 set up individual channels, it can't receive MCCH.
According to the another kind of method that sends MBMS MODIFIED SERVICES INFORMATION message,, then use MICH if UE 60 supports MICH (MBMS notification indicator channel).Yet, UE 60 can not notify RNC 20 it whether support MICH.
Therefore, when UE 60 set up individual channels, RNC 20 need go up to UE 60 at DCCH (Dedicated Control Channel) and send MBMS MODIFIED SERVICES INFORMATION message.
UE 60 sets the MBMS that selects in advance from the MBMS that the network operator provides in MBMS MODIFICATION REQUEST message, and send this MBMSMODIFICATION REQUEST message to RNC 20.Based on the MBMSMODIFICATION REQUEST message from UE 60, RNC 20 judges the MBMS that UE 60 pays close attention to.
The method that sends MBMS MODIFIED SERVICES INFORMATION message and MBMS MODIFICATION REQUEST message will be described below.
(1) method of transmission MBMS MODIFIED SERVICES INFORMATION message:
Suppose RNC 20 owing to the MBMS initiate notification that receives from CN 40 is triggered, thereby send the MBMS MODIFIED SERVICESINFORMATION message that expression MBMS starts to UE 60.
RNC 20 also sends MBMS MODIFIED SERVICES INFORMATION message at it when CN 40 receives notice about any other change that MBMS is made.
As shown in Figure 2, when RNC 20 in step 1201 when CN 40 receives the MBMS SESSION START message that expression MBMS starts, RNC 20 analyzes the sub-district of the coverage of serving as this MBMS in step 1202, and sets up radio resource.
Then, in step 1203, RNC 20 its memories of search are to seek the UE 60 that pays close attention to this MBMS.
In step 1204, RNC 20 judges whether the UE 60 that searches has set up individual channels in step 1203.
If the UE 60 that finds in step 1203 has set up individual channels, then RNC 20 sends MBMS MODIFIED SERVICESINFORMATION message to UE 60 on DCCH in step 1205.
If the UE that searches in step 1,203 60 does not set up individual channels as yet, then RNC 20 sends MBMS MODIFIED SERVICESINFORMATION message to UE 60 on MCCH or MICH.
(2) method of transmission MBMS MODIFICATION REQUEST message:
According to 3GPP, in the network configuration such as MOCN (many network operators core network), GWCN (gateway core network) or the like, a plurality of network operators can shared RNC 20, Node B 30, sub-district and frequency band.This environment is called as the network shared environment.
In the network shared environment, RNC 20 setting network network operator's in tabulation (many PLMN tabulations) as the MIB (Master Information Block) of the advertised information of system information, and this advertised information sent to UE 60.
In the network shared environment, UE 60 can choose the information on services parameter according to MBMS, in MBMS MODIFICATION REQUEST message, set the MBMS that from the MBMS that the network operator provides, selects, and can send to RNC 20 to this MBMS MODIFICATION REQUEST message.For example, by UE 60 based on to the selection of the channel on the Mobile-TV and the MBMS that selects is notified to UTRAN 10.For each MBMS that the network operator provided, definition service ID (identification information).
UE 60 is according in the process shown below (A) to (C) any one, provides the network operator of selected MBMS by notice, sets this MBMS in MBMS MODIFICATION REQUEST message.
(A) notice and the identical network operator ID of network operator ID (identification information) during many PLMN among the MIB tabulate.
(B) the network operator ID in the many PLMN tabulations among the notice MIB.
(C) be independent of MIB ground and send network operator ID itself.
Because do not have standard to show UE 60 which in should use (A) to (C) clearly, therefore the process that will use depends on how UE 60 realizes.
Yet the method that more than sends MBMS MODIFIED SERVICES INFORMATION message and MBMS MODIFICATION REQUEST message has following problem:
(1) problem of the method for transmission MBMS MODIFIED SERVICES INFORMATION message:
As shown in Figure 3, when UE 60 set up individual channels, UE 60 may be in and have in transfer (handover) state of the radio link of a plurality of sub-districts (being in the soft state that hands over to a plurality of sub-districts).
In order to receive the MBMS data of MBMS, UE 60 about the MBMS control information of this MBMS (for example reads on MCCH, and receive the MBMS data based on the MBMS control information of on MCCH, reading subsequently information about the MBMS data that will receive and make up which sub-district).On MCCH, be called as MBMS and control the sub-district from the sub-district of wherein reading the MBMS control information.If UE 60 is in the transfer state, then by transfer set up with its a plurality of sub-districts of radio link in any one all be the candidate of MBMS control sub-district.The sub-district that is elected to be MBMS control sub-district by UE 60 can not be notified to RNC 20.
For example, suppose as shown in Figure 3 that UE 60 is connected to sub-district 1, sub-district 2 and sub-district 3 simultaneously by transfer, selected sub-district 2, and on MCCH, receive the MBMS control information from this MBMS control sub-district as MBMS control sub-district.Suppose that also sub-district 2 has started the service 2 of MBMS, and sub-district 3 has also started the service 3 of MBMS, and the service 1 of MBMS is owing to the MBMS SESSION START message from CN 40 is activated, and serve 1 coverage coverage cell 1, sub-district 4, sub-district 5 and sub-district 6, promptly, service 1 is started by sub-district 1, rather than start by sub-district 2 and sub-district 3.
The MBMS MODIFIED SERVICESINFORMATION message that RNC 20 sends about serving 1 to UE 60.Yet because MBMS MODIFIED SERVICESINFORMATION message can't send the information about the sub-district, so UE 60 may break down.
To describe this problem in detail below.
UE 60 has selected sub-district 2 as MBMS control sub-district, and can only read the MBMS control information about sub-district 2 on MCCH.In other words, UE 60 can not read the MBMS control information about sub-district 1 on MCCH, and the result just can not receive the MBMS data according to service 1.
Because UE 60 is connected to sub-district 1, sub-district 2 and sub-district 3 simultaneously by transferring, so the MBMS MODIFIED SERVICES INFORMATION message that on DCCH, sends about serving 1 to UE 60 by sub-district 1, sub-district 2 and sub-district 3 of RNC20.At this moment, as mentioned above, the MBMS MODIFIED SERVICESINFORMATION message that sends to UE 60 from RNC 20 can not send the information about the sub-district.
Therefore, UE 60 can't identify about serving 1 MBMS MODIFIED SERVICESINFORMATION message to be sent to which sub-district, can't judge that therefore which sub-district has started service 1.
As a result, such problem appears, that is, and and the MBMSMODIFIED SERVICES INFORMATION message that UE 60 handles about serving 1, and, though it can not receive the MBMS data according to service 1, attempt receiving the MBMS data according to service 1.
Depend on its ability, UE 60 may not receive the MBMS data simultaneously according to a plurality of MBMS, and may not receive the MBMS data simultaneously according to MBMS and other services except that MBMS (ordinary groups service).When such UE 60 receives on DCCH when serving 1 MBMS MODIFIED SERVICES INFORMATION message, it to serve 1 and the current MBMS that has received and other services except that MBMS distinguish priority.
If it is higher to serve 1 priority, such problem then appears, promptly, according to the activation release of PDF context request process, UE 60 finish have lower priority, the current MBMS that has received and other services except that MBMS, thereby carry out the carrier dispose procedure according to the activation release of PDF context request process, so that receive the MBMS data according to service 1.
(2) problem of the method for transmission MBMS MODIFICATION REQUEST message:
As mentioned above, process (A) to (C) can be used for notifying the network operator that selected MBMS is provided for UE 60 in MBMSMODIFICATION REQUEST message.
Process (A), (B) are the processes that is used for according to advertised information is simplified and informing network is runed ID.Yet because the MBMS MODIFICATIONREQUEST message that sends to RNC 20 from UE 60 can not send the information about the sub-district, so RNC 20 may break down in the network shared environment according to process (A), (B).
To describe this problem in detail below.
Fig. 4 shows network and shares configuration, and wherein three network operators' SGSN 50 is connected to single RNC 20.Fig. 4 shows the relation between SGSN 50 and the RNC 20, and which network operator Fig. 5 shows and control each sub-district.
As shown in Figure 5, will analyze such a case, and wherein, be controlled by network operator's 1 sub-district 1, network operator 2 sub-district 2 and network operator 3 sub-district 3 as the RNC20 of higher level device, promptly RNC 20 is shared by a plurality of network operators.In the case, hypothetical network network operator 1 the service with service ID=1 is just carried out by sub-district 1, and network operator 2 the service with service ID=1 is just carried out by sub-district 2, and network operator 3 the service with service ID=1 is just carried out by sub-district 3.Yet, because the MBMS service has the service ID for each network operator's definition, differing from one another if therefore have the network operator ID of the service of a service ID, these services may be not necessarily identical.Suppose that also UE 60 is connected to sub-district 1, sub-district 2 and sub-district 3 simultaneously by transferring, and read advertised information from sub-district 2.
Under situation shown in Figure 5, suppose that UE 60 has sent MBMS MODIFICATIONREQUEST message according to process (A) or (B) to RNC 20 in step 1601 shown in Figure 6,1602.
Yet as mentioned above, MBMS MODIFICATION REQUEST message can not send the information about the sub-district.
Therefore, RNC 20 can't identify UE 60 according to MBMS MODIFICATION REQUEST message and which sub-district to read advertised information from.As a result, when UE 60 according to the process of simplifying (A) or (B) during informing network network operator ID, it is the network operator of sub-district 1 or sub-district 3 rather than sub-district 2 that RNC 20 may take for the network operator that UE 60 selects.
If RNC 20 has misread the network operator that UE 60 selects, then RNC 20 can't correctly be changed to UE 60 notifying MBMSs.
As mentioned above, the problem of MBMS MODIFIED SERVICES INFORMATION message and MBMS MODIFICATION REQUEST message is that they can not send information about the sub-district.

The method that sends MBMS MODIFIED SERVICESINFORMATION message and MBMS MODIFICATION REQUEST message according to this exemplary embodiment will be described below.
(1) method of transmission MBMS MODIFIED SERVICES INFORMATION message:
Suppose that RNC 20 is triggered owing to receiving the notice that starts from the MBMS of CN 40 service 1, thereby send the MBMS MODIFIED SERVICESINFORMATION message that expression service 1 starts to UE 60.RNC 20 also receives from CN 40 at it and sends MBMS MODIFIED SERVICES INFORMATION message about to the notice of any other change of MBMS the time.
As shown in Figure 3, suppose that UE 60 is connected to sub-district 1, sub-district 2 and sub-district 3 simultaneously by transferring, select sub-district 2, and on MCCH, receive the MBMS control information from MBMS control sub-district as MBMS control sub-district.Suppose that also sub-district 2 has started the service 2 of MBMS, and sub-district 3 has also started the service 3 of MBMS.
As shown in figure 14, when RNC 20 in step 801 when CN 40 receives the MBMS SESSION START message that the service 1 of expression MBMS starts, RNC 20 analyzes the sub-district of the coverage of serving as this MBMS in step 802, and sets up radio resource.Suppose coverage coverage cell 1, sub-district 4, sub-district 5 and the sub-district 6 of service 1.
Then, RNC 20 searches for the service paid close attention to 1 and is present in UE 60 in the coverage of service 1 in step 803, and judges in step 804 subsequently whether the UE 60 that searches in step 803 is in the state of setting up individual channels.In other words, the sub-district that meets the following conditions of RNC 20 search: this sub-district is " sub-district in the coverage of the service of being included in 1 " and be " UE 60 that is in the state of setting up individual channels is connected to the sub-district by transfer ".Suppose that the sub-district 1 with sub-district ID=1 satisfies these conditions.
